STANISLAW PAUL ZYWNO, OF MIDDLETOWN, CONNECTICUT.

FLYING-MACHINE.

To all whom it may concern:

Be it known that I, STANISLAW PAUL ZYWNO, a citizen of Russian ing at Middletown, in the county of Middlesex and State of Connecticut, have invented certain new and useful Improvements in Flying-Machines, of which the following is a specification.

My invention relates to improvements in flying machines, and the object of my improvement is to produce a flying machine that operates by the vibration of a pair of wings after the manner of a bird.

In the accompanying drawing Figure 1 is a plan view of my improved flying machine.

Fig. 2 's a sectional view on the line w m of Fig. 1.

Fig. 3 is a rear elevation on an enlarged scale of the main shaft and crank arms.

Fig. 1 is a similar view of the maingear and connected gearing.

Fig. 5 is aside elevation. of the same.

Fig. 6 is a rear elevation of the controller arm and connected parts.

Fig. 7 is a side elevation of the same.

Fig. 8 is a side elevation of the machine, on the same scale as Fig. 1.

My improved flying machine comprises a pair of lateral wings 10 positioned one on each side of a central house or cab structure 11 that are supported and inter-connected so as to vibrate in unison, and operated by a motor 12 of any suitable form.

The house 11 isa skeleton structure of appreciable width and length and is covered with or other sheet material, the said roof 13 be ing of suitable area to have an appreciable efiect as an air plane when the machine is operated at high speed. The side walls 1A support near the upper end a transversely extending control shaft 15, the ends 16 of which project outwardly laterally, and below the control shaft 15 is a countershaft 17 On the control shaft 15 is mounted a control gear 18 that cooperates with a sector 19.

The said sector 19 is provided on the upper end of an arm 20 that is mounted on the couritershaft 17, the said arm 20 extending downwardly within the house 11 and being provided with means for being moved to diflerent positions and for being locked in any particular position to which it may Poland, resid-.

be set.. By moving the arm 20 back and forth the control shaft 15 is rotated correspondingly, and the wings 10 are so connected to the control shaft 15 that they are tilted as the control shaft 15 is rotated.

As one means of operating the arm 20 I provide on the lower end' thereof a second sector 50 that engages with a worm 51 provided on the worm shaft 52.

At one end of the worm shaft 52 and located in a convenient position to be manipulated by the operator I provide a crank arm 53. The wings 10 are connected to the ends 16 of the control shaft 15 by a pivotal connection 21 that permits of a generally up and down swinging movement of the wings 10.

The lower part 22, of the house 11 is formed suitably to provide a bed for the motor 12 and to support the middle part of the main shaft 23. Extending downwardly from the house 11 is acradle structure 24 that is provided with a pair of wheels 25 of the usual form. v

At the lower part of the house 11. and extending laterally from the bed 22 and along the main shaft 23 is a frame 26 of suitable light and strong construction for operatively supporting the outer end portions of the main shaft 23.

The main shaft 23 is provided at about the middle with a main gear 27 that is oper atively connected with the motor 12 by a set of gears 28 and at the ends is provided with a pair of crank arms 29 that are connected with the wings 10 in a manner to be described. The connections to the crank arms 29 comprise in each case a block 30 pivotally mounted on the crank pin 31, the said block 30 having on the upper end a short, longitudinally extending pivotal pin 32 that serves as the means for connection withthe upwardly extending connecting rod 33, the case as described of a combination that permits of raising and lowering the connecting rod 33 and at the same time permits of swinging the same back and forth, after the The wings 10 extend laterally from the 7 ends 16 of the control shaft 15 and are built up of a border frame 36 having a longitudin'al cross-rib 37 at about the middle and covered with a web 38 of thin sheet alumimovement for a particular setting inforce the same. 30

num, being of aboutthe same length as the house 11 and having a lateral extent of about three times the width of the said house 11. The border frame 36 may be of shallow V-shape along the edge opposed to the house 11, the front edge 40 and rear edge 41' being directed laterally in parallelism,

and the outer'lateral edge 42 being rounded as shown. At the middle of the longitudinal cross-rib 37 is the downwardly directed strut rod 35 on the lower side and on the upperside is the upwardly directed strut rod 42, the lower strut rod 35 being connected to the connectin rod 33 as described, and from the ends of t e said strut rods 35 and 42 is provided a net-work of strain or tie wires, comprising the upper 'set 48 of tie wires on the upper side and the lower set 44 of tie wires on the lower side, the outer ends of, the Wires being connected to different parts of the border frame 36 suitably to re- Extending rearwardly from the house 11 is structure and mechanism of ordinary form, comprising the tail structure 45, the lateral rudder 46 atthe rear end thereof, and adjacent the said rear end is a pair of laterally positioned I elevation control wings 47.

Lines 48 are connected to the end rudder 46 .to move the same from side to side to control the lateral direction of movement and lines 49 connected to the shaft 54 of the elevation control wings 47 operate to control the angular position of the same to control the upward and downward move- ,ment, the control wings 47 "being 'tiltedin the usual manner to effect a "change in the upward or-downward direction; r The elevation control wings 47 are. used ordinarily to control upward and downward main wings 10, and the latter aretilted by operating the arm 20 to effect a more proof the 15 to which they are connected. When the main wings 10 are tilted so that they are inclined from the rear downwardly relatively to the directionof movement and they are vibrated at a high rate of speed the operation on the air is such as to elevate the machine, the rate of vibration being so rapid that the air offers resistance that is positive and momentarily essentially like a solid or liquid body'.

As described the motive feature of my flying'machine comprises a pair of vibrating wings, operated by a suitable motor, and

incomunction therewith the house with its flat covered roof operates as a diminutive plane for steadying the movement.

f I claim as my invention In combination in a flying machine, a-

house having a skeleton frame structure, a tail structurei extending rearwardly from the said house, a lateral rudder mounted on the end'of'the saidtail, a pair of elevation control wings mounted on the said tail, means for tilting the, said} wings, an air plane serving as the roof for the said house, a control shaft extending through the upper part of the said house, means for ro- .tating the said control shaft, a main shaft extending through the said house, amotor operatively connected to the said main shaft,

crank arms on the ends of the "said main shaft,a vpair of main wings connected each by one end to one of the ends of the 'said control shaft, and connecting rods serving to operatively connect the body portion of each'of the said main wings with one of the said crank arms.
